I'm new to Linux and Steam so I apologize for probably not knowing what you're looking for. I installed Steam on Linux Mint 19.1. Steam worked fine but I couldn't get Galaxy Control working. After researching the issue, I discovered I needed to install Vulkan. After installing Vulkan the game works great except that I cannot see any army or ships. Not mine in base or when attacking and not anyone else's, either. Not even when I do a replay. Nothing shows except the buildings. I only see a shadow where the men/ships are and can see them firing but cannot see the actual men/ships themselves.
